Description

Metal-like pattern forming device and method for manufacturing metal-like pattern film

Technical Field

The present invention relates to a brush pattern forming apparatus and a method for manufacturing a brush pattern film, and more particularly to a metal-like brush pattern forming apparatus and a method for manufacturing a metal-like brush pattern film.

Background

The metal-like brushed pattern film can be applied to various steel plate decorations (for example, products such as refrigerators, washing machines and audios) and building material decorations and other fields. The metal-like lines of the metal-like pattern brushing film can improve the attractiveness of the product, and further improve the value of the product.

In the prior art, different methods are known for processing thin film materials to form metallic-like brush lines films having brush lines (e.g., metallic-like brush lines). For example, the prior art method includes coating an ultraviolet light coating on a surface of a film material, embossing the film material coated with the ultraviolet light coating by a wheel having an embossing, and crosslinking and hardening a portion of the ultraviolet light coating on the film material under a specific condition, thereby forming a brushed-grained film product having a pattern identical to or corresponding to that on the wheel.

In addition, in the prior art, the surface of the film material may be polished by using a polishing material, so as to form brush lines or scratches on the surface of the film material, thereby forming a brush line film product. Referring to fig. 1, fig. 1 is a schematic diagram of a brush pattern forming apparatus in the prior art. In the brush pattern forming device D' shown in fig. 1, a brush pattern film product is formed by two sets of conveying and winding units.

Specifically, as shown in fig. 1, a substrate S (e.g., a film material made of a plastic material) is conveyed between a conveying unit 1 'and a take-up unit 2', and an abrasive material, such as sandpaper P, is conveyed between the conveying unit 1 "and the take-up unit 2". The substrate S and the sandpaper P contact each other at the pattern brushing unit 4 ', and the sandpaper P is scraped to the surface of the substrate S to form a pattern by fixing the fixing wheel 41' (also referred to as a pressing wheel) of the pattern brushing unit 4 'and the grinding wheel 42'.

However, in the above-described prior art method, the use of the ultraviolet coating causes additional manufacturing costs and the manufacturing steps are complicated involving the use of curing equipment. On the other hand, in the method using two sets of conveying and winding units, the quality of the metal-like brushed film is easily affected by the flatness of the surface of the fixed wheel 41', so that if a metal layer is subsequently disposed on the substrate S by the vapor deposition manufacturing method, the metal layer may not be uniform. In other words, the prior art still has the disadvantages of high cost and low product yield.

These terms are used primarily to distinguish one element from another element or from one signal to another signal. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.

Please refer to fig. 2 to fig. 4. Fig. 2 to fig. 4 are schematic diagrams of a metal-like brush pattern forming device according to different embodiments of the present invention. First, as shown in fig. 1, a metal-like pattern forming apparatus D according to an embodiment of the present invention includes a conveying unit 1, a winding unit 2, a fixing unit 3, and a first pattern unit 4. The fixing unit 3 is disposed between the conveying unit 1 and the winding unit 2 and includes a first fixing clamp 31 and a second fixing clamp 32, and the first pattern brushing unit 4 is disposed between the first fixing clamp 31 and the second fixing clamp 32.

Specifically, the conveying unit 1 may be a feeder (rewinder) for unwinding the rolled substrate S and conveying the unwound substrate S to the processing equipment for processing, and the winding unit 2 may be a winder (winder) for winding the processed substrate S (e.g., the substrate S formed with the brush marks) into a roll. In other words, in the metallic brush mark forming device D, the substrate S is conveyed in the first direction D1 between the conveying unit 1 and the winding unit 2.

In an embodiment of the invention, the transport unit 1 and the take-up unit 2 cooperate such that the substrate S travelling therebetween is produced at a rate of between about 10 and 50 meters per minute. In one embodiment, the production rate of the substrate S is about 30 meters.

In an embodiment of the present invention, the substrate S may be a film made of a plastic material. For example, the substrate S may be a polyethylene terephthalate (PET) film. In addition, the substrate S may have a thickness of between 25 to 100 micrometers (μm). However, the present invention is not limited thereto.

Next, as described above, the fixing unit 3 includes the first fixing jig 31 and the second fixing jig 32. The first fixing jig 31 is disposed at a position close to the conveying unit 1, and the second fixing jig 32 is disposed at a position close to the winding unit 2. The first fixing clamp 31 and the second fixing clamp 32 are used for supporting and fixing the substrate S conveyed by the conveying unit 1, and may be wheels rotating in the same direction as the conveying unit 1 and the winding unit 2, respectively. In other words, the first fixing clamp 31 and the second fixing clamp 32 rotate along with the substrate S being transported on the production line, and can apply a clamping force to the substrate S.

In one embodiment of the present invention, the first fixing jig 31 and the second fixing jig 32 are rotated in the same direction, however, the rotation rate (rotation speed) of the first fixing jig 31 is different from the rotation rate of the second fixing jig 32. Specifically, the rotation rate of the first fixing jig 31 is lower than that of the second fixing jig 32. In this way, in the process of forming the brush pattern on the surface of the substrate S, the substrate S is stretched and tightened by the design of the difference between the rotation rates of the first fixing clamp 31 and the second fixing clamp 32, so that the formation of the brush pattern is facilitated, and the substrate S can be prevented from wrinkling during rolling. However, the present invention is not limited to the above embodiments.

Next, as described above, the first brush unit 4 is disposed between the first fixing jig 31 and the second fixing jig 32. The first corrugation unit 4 is a tool for performing corrugation forming on the surface S1 of the substrate S. Specifically, in the embodiment of the present invention, the first graining unit 4 includes at least two first fixed wheels 41 and a first grinding wheel 42. As shown in fig. 2, two first fixed wheels 41 and a first grinding wheel 42 are provided at positions on two opposite surfaces of the substrate S, respectively. In the embodiment of the present invention, the first grinding wheel 42 is disposed on the surface S1 of the substrate S intended to be brushed, and the two first fixed wheels 41 are disposed on the surface (not shown in fig. 1) opposite to the surface S1.

In the embodiment of the present invention, the first grinding wheel 42 includes two rotating wheels 421, and the first sandpaper P1 surrounding the two rotating wheels 421 can be made to run on the first grinding wheel 42 by the operation of the two rotating wheels 421.

In addition, the first sandpaper P1 is pressed against the first grinding wheel 42 by the cooperation of the two first fixed wheels 41. The first sandpaper P1 can grind and scratch the surface S1 of the substrate S, thereby forming a brush pattern on the surface S1 of the substrate S. In fact, by adjusting the clamping force between the two first fixed wheels 41 and the first grinding wheel 42, the force with which the substrate S and the first sandpaper P1 passing between the two first fixed wheels 41 and the first grinding wheel 42 abut against each other can be adjusted, thereby controlling the depth and pattern of the formed brush pattern.

As mentioned above, the two first fixing wheels 41 may be wheels that rotate along with the advance of the substrate S (transported by the cooperation of the conveying unit 1 and the winding unit 2), and the rotation directions of the two first fixing wheels 41 may be the same as those of the first fixing jig 31 and the second fixing jig 32 of the conveying unit 1, the winding unit 2, and the fixing unit 3.

On the other hand, the first grinding wheel 42 may be a rotatable wheel. However, the rotation direction R1 of the first grinding wheel 42 may be the same as or different from the first fixing jig 31 and the second fixing jig 32 of the carrying unit 1, the winding unit 2, and the fixing unit 3. Specifically, the rotation direction R1 of the first grinding wheel 42 may be changed depending on the topography of the brush lines desired to be formed on the surface S1 of the substrate S. In the embodiment shown in fig. 1, the direction of rotation R1 of the first grinding wheel 42 is different from the first fixing jig 31 and the second fixing jig 32 of the conveying unit 1, the winding unit 2, and the fixing unit 3.

For example, as shown in fig. 2, the rotation direction R1 of the first grinding wheel 42 is counterclockwise, and the conveying unit 1 and the winding unit 2 rotate counterclockwise in order to convey the substrate S therebetween along the first direction D1. In other words, the direction of rotation of the first grinding wheel 42 may be such that the first grinding wheel 42 imparts a force to the running substrate S opposite to the running direction (first direction D1). Thus, substrate S and first sandpaper P1 have opposite running directions at the point where they contact each other.

By designing the direction of rotation of the first grinding wheel 42, natural and fine brush lines can be formed on the surface S1 of the base material S. Besides, the first grinding wheel 42 may have the same or different rotation rate as the first fixing jig 31 and the second fixing jig 3 of the conveying unit 1, the winding unit 2, and the fixing unit 3, respectively. The rotation rate of the second grinding wheel 42 can also be adjusted according to actual requirements. For example, the rotation rate of the second grinding wheel may be lower than the rotation rates of the conveying unit 1 and the fixing unit 3.

In summary, through the design of the metal brush pattern forming device D, the substrate S passes through the first fixing clamp 31, the first brush pattern unit 4 and the second fixing clamp 32 in sequence through the cooperation of the conveying unit 1 and the winding unit 2, and the surface S1 of the substrate S is processed by the first brush pattern unit 4 to form at least one type of metal brush pattern.

Please refer to fig. 3. As mentioned above, fig. 3 is a schematic view of a metal-like brush pattern forming device D according to another embodiment of the present invention. The main difference between the embodiment shown in fig. 3 and the embodiment shown in fig. 2 is that in the embodiment shown in fig. 3, the metal-like brush pattern forming device D further includes a second brush pattern unit 5 and a cleaning unit 6.

Specifically, in the embodiment shown in fig. 3, two sets of brush pattern units (the first brush pattern unit 4 and the second brush pattern unit 5) are used to process the surface S1 of the substrate S simultaneously. The second brush pattern unit 5 is disposed between the first brush pattern unit 4 and the second fixing jig 32. Like the design of the first stripping unit 4, the second stripping unit 5 comprises at least two second fixed wheels 51 and a second grinding wheel 52. The functions and characteristics of the two first fixed wheels 51 and the second grinding wheels 52 of the second brush-grain unit 5 are similar to those of the two first fixed wheels 41 and the first grinding wheels 42 of the first brush-grain unit 4, and will not be described again. For example, the second grinding wheel 52 includes two rotating wheels 521, and the second sandpaper P2 surrounding the two rotating wheels 521 can be made to run on the second grinding wheel 52 by the operation of the two rotating wheels 521.

It is noted, however, that in one embodiment of the present invention, the first grinding wheel 42 and the second grinding wheel 52 rotate in opposite directions. Specifically, as shown in fig. 3, the direction of rotation R1 of the first grinding wheel 42 is opposite to the direction of rotation R2 of the second grinding wheel 52, wherein the direction of rotation R1 of the first grinding wheel 42 is counterclockwise and the direction of rotation R2 of the second grinding wheel 52 is clockwise. In other words, the first grinding wheel 42 can apply a force to the running substrate S opposite to the running direction thereof (the first direction D1), while the second grinding wheel 52 rotates in the same direction as the transport unit 1 and the take-up unit 2.

By designing the rotation directions R1 and R2, the brush lines formed on the surface S1 of the substrate S can be made natural and fine, so that the manufactured metal-like brush line film has a similar appearance to that of a metal material, i.e., high fidelity. Specifically, in the embodiment of the present invention, by using more than two sets of brush pattern forming devices, and adjusting the rotation directions and rotation rates of the two sets of brush pattern forming devices (such as the first brush pattern unit 4 and the second brush pattern unit 5 shown in fig. 3), metal-like brush patterns with uniform, natural distribution and high fidelity can be formed on the surface S1 of the substrate S.

In addition, as in the design of the first graining unit 4, in the second graining unit 5, the second sandpaper P2 is abutted against the second grinding wheel 52 by the cooperation of the two second fixed wheels 51. The mechanism of forming the brush lines on the surface S1 of the substrate S by using the second coated abrasive P2 is similar to the first coated abrasive P1 in the first brush line unit 4, and will not be described again. It is worth mentioning, however, that in one embodiment of the present invention, the roughness of the first sandpaper P1 in the first pattern unit 4 is greater than the roughness of the second sandpaper P2 in the second pattern unit 5.

In other words, the surface S1 of the substrate S was first patterned with a first sandpaper P1 having a lower roughness (lower double gauge) and then patterned with a second sandpaper P2 having a higher roughness (higher double gauge). The first set of brush lines and the second set of brush lines can together form a metallic-like brush line on the surface of the finished product. The topography of the metallic brush pattern can be made more natural by using sandpaper having different roughness and grinding the surface S1 of the substrate S in order from low roughness to high roughness. However, the above description is only one embodiment of the present invention, and the present invention is not limited thereto.

Next, please refer to fig. 3 again. The removing unit 6 included in the metal-like brush pattern forming apparatus D shown in fig. 3 may be a removing wheel. The removing unit 6 is disposed between the second fixing clamp 32 and the winding unit 2, and the flocks generated by the first brush-line unit 4 and/or the second brush-line unit 5 are removed by the treatment of the removing unit 6.

Specifically, in the process of forming the brush line on the surface S1 of the substrate S by the first brush line unit 4 and/or the second brush line unit 5, a part of the material of the substrate S itself is scraped off or scraped off. As a result, the lint or dust to be removed may remain on the substrate S passing through the first pattern unit 4 and/or the second pattern unit 5. The removing unit 6 may remove the lint by a brush or other mechanism so that the surface of the substrate S is kept clean. In one embodiment of the present invention, the removing unit 6 may remove more than 90% of the remaining lint.

Next, please refer to fig. 4. Fig. 4 is a schematic view of a metal-like pattern forming apparatus according to another embodiment of the present invention. The main difference between the embodiment shown in fig. 4 and the previous embodiment is that the metal-like brush pattern forming device D shown in fig. 4 includes four sets of brush pattern units. It should be noted that, in the present invention, the number of the brush-line units in the metal-like brush-line forming device D is not limited, but can be adjusted according to actual requirements.

As shown in fig. 4, the metal-like brush pattern forming device D includes a first brush pattern unit 4, a second brush pattern unit 5, a third brush pattern unit 7, and a fourth brush pattern unit 8. As shown in the first and

second graining units

4 and 5, the third graining unit 7 includes two third fixed wheels 71 and a third grinding wheel 72, and the fourth graining unit 8 includes two fourth fixed wheels 81 and a fourth grinding wheel 82.

The third grinding wheel 72 is comprised of two rotating wheels 721, and by the operation of the two rotating wheels 721, a third piece of sandpaper P3 that surrounds the two rotating wheels 721 can be made to run on the third grinding wheel 72. The fourth grinding wheel 82 is comprised of two wheels 821 and a fourth sandpaper P4 surrounding the two wheels 821 is made to travel over the fourth grinding wheel 82 by the operation of the two wheels 821.

Specifically, the details of the third and

fourth brush units

7 and 8 are similar to those of the first and

second brush units

4 and 5 described earlier. It should be noted, however, that in the embodiment shown in fig. 4, the rotation speed of the grinding wheels in the four groups of the brush-line units is specially designed.

As shown in fig. 4, the direction of rotation R1 of the first grinding wheel 42 is the same as the direction of rotation R2 of the second grinding wheel 52, and the direction of rotation R3 of the third grinding wheel 72 is the same as the direction of rotation R4 of the fourth grinding wheel. In addition, the rotational direction R1 and the rotational direction R2 are opposite to the rotational direction R3 and the rotational direction R4. For example, the direction of rotation R1 of the first grinding wheel 42 and the direction of rotation R2 of the second grinding wheel 52 are both counterclockwise, while the direction of rotation R3 of the third grinding wheel 72 and the direction of rotation R4 of the fourth grinding wheel 82 are both clockwise.

In other words, in the embodiment shown in fig. 4, the appearance of the metallic-like scrub film thus manufactured can be improved by devising the rotation direction of the grinding wheel in different scrub units. In addition, the rotation rates of the first grinding wheel 42, the second grinding wheel 52, the third grinding wheel 72 and the fourth grinding wheel 82 may be adjusted. In addition, as in the previous embodiments, the roughness of the sandpaper in the different graining units may also be adjusted. For example, the high-to-low arrangement of sandpaper roughness may be, in order, first sandpaper P1, second sandpaper P2, third sandpaper P3, and fourth sandpaper P4.

In summary, with the metallic-like pattern forming apparatus D provided in the embodiment of the present invention, a metallic-like pattern film (i.e., the substrate S with the surface S subjected to pattern processing) can be manufactured by passing the substrate S through the pattern forming apparatus (including at least the first pattern forming apparatus 4) through a single set of the conveying and winding units (the conveying unit 1 and the winding unit 2).

In addition, the invention also provides a manufacturing method of the metal-like brushed film. Referring to fig. 7, fig. 7 is a flowchart illustrating a method for fabricating a metal-like damascene film according to an embodiment of the present invention. The method for manufacturing the metal-like brushed film comprises the following steps: conveying the substrate by a conveying unit (step S100); clamping the substrate by a fixing unit (S102); forming brush lines on the surface of the substrate by a first brush line unit (S104); and winding the base material on which the brush lines are formed by the winding unit (S108).

In addition, as shown in fig. 7, in addition to the above listed steps S100, S102, S104 and S108, the method for manufacturing a metal-like brushed film according to the present invention may further include: forming another brush line on the surface of the base material through the second brush line unit (step S106); cleaning the surface of the substrate by a cleaning device (step S110) to remove dust attached to the surface of the substrate; and plating a metal layer on the surface of the substrate by an evaporation device (step S112) to form a metal-like texture film. However, the present invention is not limited thereto.

It should be noted that the method for manufacturing a metal-like damascene film provided in the embodiments of the present invention is not necessarily performed in the order of the above steps. For example, the step of conveying the substrate by the conveying unit (step S100) and the step of winding the substrate formed with the brush stripes by the winding unit (step S108) may be performed simultaneously. In other words, in the process of processing, the conveying unit continuously performs conveying of the substrate, and the winding unit continuously performs winding of the processed substrate. Likewise, the first embossing unit is also continuously processing the running substrate S. Therefore, in the method for manufacturing a metal-like damascene film, the order of the steps is described substantially in the order in which the substrate passes through.

In fact, the method for manufacturing a metal-like brushed pattern film according to the present invention can be performed by the metal-like brushed pattern forming apparatus D. Therefore, referring to fig. 2 to 4, the conveying unit 1, the fixing unit 3, the first thread brushing unit 4 and the winding unit 2 are disposed along the production line, the fixing unit 3 is disposed between the conveying unit 1 and the winding unit 2, and the fixing unit 3 includes a first fixing clamp 31 and a second fixing clamp 32. The first brush pattern unit 4 is disposed between the first fixing jig 31 and the second fixing jig 32.

In one embodiment, the first fixing clamp 31 has a rotational speed lower than the rotational speed (rotational speed) of the second fixing clamp 32. Details of the control of the rotation speeds of the first fixing jig 31 and the second fixing jig 32 are as described in the foregoing description of the metallic brush pattern forming apparatus D.

When the method for manufacturing a metal-like scrub film according to the present invention is performed using the metal-like scrub forming device D shown in fig. 3, the second scrub unit 5 may be disposed between the first scrub unit 4 and the second fixing jig 32, as described above. In addition, the first grain brushing unit 4 includes at least two first fixed wheels 41 and a first grinding wheel 42, the second grain brushing unit 5 includes at least two second fixed wheels 51 and a second grinding wheel 52, and the rotation directions of the first grinding wheel 42 and the second grinding wheel 52 are opposite.

In addition, in the method for manufacturing a metal-like brushed film, the first sandpaper P1 may be abutted against the first sandpaper 42 by the cooperation of the two first fixed wheels 41, the second sandpaper P2 may be abutted against the second sandpaper 52 by the cooperation of the two second fixed wheels 51, and the roughness of the first sandpaper P1 is greater than that of the second sandpaper P2.

The method for producing a metal-like pattern film according to the present invention may be carried out by using a metal-like pattern forming apparatus D shown in fig. 4. Accordingly, the method for manufacturing a metal-like brushed film provided by the present invention may further include a step of processing the surface S1 of the substrate S by the third brushing unit 7 and the fourth brushing unit 8. The details of the above steps are the same as those described above with respect to fig. 4, and will not be described again here.

After the surface S1 of the substrate S is processed by the metallic-like pattern forming apparatus D shown in fig. 2 to 4, the substrate S on which the brush lines have been formed may be further cleaned and plated to form a metallic-like pattern film as described in the previous step S110 and step S112.

Please refer to fig. 5 and fig. 6. Fig. 5 is a schematic view of a cleaning apparatus used in one embodiment of the present invention, and fig. 6 is a schematic view of an evaporation apparatus used in one embodiment of the present invention.

First, as shown in fig. 5, the cleaning apparatus may be a water cleaning apparatus which may run the substrate S formed with the brush lines on-line through a set of conveying and winding mechanisms (not numbered). First, the surface S1 of the substrate S is cleaned by the first water cleaning unit W1 and then dried by the first drying unit B1. Next, the surface S2 of the substrate S opposite to the surface S1 is washed by the second water washing unit W2 and dried by the second drying unit B2.

Specifically, the first and second washing units W1 and W2 may be washing mechanisms of a washing wheel, and the first and second drying units B1 and B2 may be ovens having a step-type heating function, respectively. In one embodiment of the present invention, the first drying unit B1 may sequentially provide the substrate S with a temperature of 90 ℃/110 ℃/100 ℃, and the second drying unit B2 may sequentially provide the substrate S with a temperature of 90 ℃/100 ℃/110 ℃/100 ℃.

In addition, the step S110 of cleaning the surface of the substrate S by the cleaning apparatus (S1, S2) may be repeated. In one embodiment of the present invention, the step S110 is repeated twice to ensure the removal rate of the lint or the dust. However, the present invention is not limited thereto.

Next, please refer to fig. 6. Specifically, the cleaned substrate S may then be transported in a third direction D3 by an evaporation apparatus to plate the metal layer M on the surface S1 of the substrate S. For example, the evaporation apparatus may include a container E for carrying a plating solution containing a metal material, and the metal material (e.g., aluminum) is plated on the surface S1 of the substrate S by an evaporation process to form a two-layer structure. The double-layer structure comprising the substrate S subjected to the pattern brushing and the metal layer M can be rolled to form a metal-like pattern brushing film product.

Advantageous effects of the embodiments
